Scroll content automatically in an overflow:none e

I have mixed content (images, text) in an overflow:none element. Now, I'd like to automatically scroll that content in x/y axis based on the location of the mouse pointer. Overflow:auto wouldn't be an option, as I wouldn't like to show/use the scrollbars in that element.

I've found a script which does something similar, but only with the background image. Is there a way to have a similar effect but with moving the whole content of the div? Thank you for your answers in advance!

This was a fun one! Change it so you move the scrollTop and scrollLeft instead of background position. Since you have a percentage you could calculate the of scrollTop and scrollLeft like so. Check out the fiddle.

$(document).ready(function(){
    var viewer = $('#viewer'),
        vH = viewer.height(),
        vW = viewer.width(),
        vT = viewer.offset().top,
        vL = viewer.offset().left,
        sTop = viewer.find(':first').height() + 18 - vH,
        sLeft = viewer.find(':first').width() + 18 - vW;
    // the sTop and sLeft could be calculated differently. In this case 
    // I am assuming that the viewer has a single child that is larger than itself.
    // realistically this should check total possible scrollTop and scrollLeft

    $('#viewer').mousemove(function(e){
        var $this = $(this),
            y = (e.pageY-vT)/vH,
            x = (e.pageX-vL)/vW;
        $this.scrollTop(Math.round(sTop * y))
            .scrollLeft(Math.round(sLeft * x));
    });
});
